A predicting platform for designing semiconductor quantum devices

PRESQUE received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No: 840550.

The aim of the project was to develop the first simulation model for semiconducting qubit technologies that is parametrized from experimental data on a large number of components.

Goal of PRESQUE: Revealing the physics behind the operation of quantum devices.

Semiconducting quantum devices are currently the workhorse of the EU in the road towards qubit technologies and other quantum-based devices. However, the simulation of these devices is not as advanced. The methods that are used to numerically compare experimental results and explain them are not standard, and as a result, not easily reproducible. Through this project, we were able to provide the first demonstration of a simulation model of Quantum Point Contacts of various shapes and sizes, which were fabricated in the lab. The results revealed the most prevalent physical phenomena that take place inside them, a valuable insight for the fabrication of electron flying qubits. The methods that were used are comprehensive, and therefore provide a standardized, and faster (optimized) way  of solving similar problems. This can significantly reduce the overhead of preparing custom-made simulations and point towards optimum device designs.
